To aZZ whom it may concern.-

Beitknown that I, ROBERT H. DOWLING, a citizen of the United States, and a resident of Newark, in the county of Licking and State of Ohio, haveinvcnted certain new and useful linprovenientsin OarOouplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains 0 to make and use the same, reference being had to the accompanying drawings, and to letters or figures of referen ce marked thereon, which form a .part of this specification.

Figure 1 of the drawings is a representation of this invention,and is a front view. Fig. 21s top view. Fig. 3 is a top view of the lower half of the coupling, showing the locking-jaw closed. Figs. 4, 5, 6, -7, and 8 are details.

The invention relates to improvements in car-couplings; and it consists in the construction and novel combination of parts, as here inafter set forth.

Referring to the drawings, A designates the end sill of a car, and B shows the draw-bar secured to the under side of the sill in the ordinary manner. The draw-bar B and the drawhead 0 are preferably cast in two integral longitudinal sections, as shown at a and a, adapted to fit closely together, and dowel-pins b are provided to secure the parts from lateral displacement. The upper side of the draw head is provided with an upstandi nglug, 0, designed to strike against a buffer-head and relieve the coupling from shock while connecting the cars. The front face of the draw-head O is of a general concave form in cross-section, as shown in the drawings.

1) represents the looking or coupling jaw, which in a closed position extends half-way across the face of the draw-head and ata proper distance therefrom to allow the entrance of the similar coupling of an adjacent car. The shank E of the coupling-jaw stands at nearly right angles thereto and extends into the recess cin the draw-head, where it is held by the trunnions 0, having pivotal bearingsin the recesses (Z. The shoulders e on the shank E are de signed to abut against the shoulders e in the draw-head, and the curved endf of the shank is adapted to turn easily against the curved wall f within the recess, so that the trunnions prevent said pin from-turning.

are relieved from direct strain. A crank-arm,

F, has its crank portion extending. upwardly through the wall of the draw-head and into an opening in the lower trunnion, and the guard 5 g is designed to enter a corresponding recess,

9, in the side of the trunnion-opening. The crank-arm F is provided at its outer end with an eye, from which the operating-rod G extends through a ring-bearing, h, to the outer 6c side of the car.

H is the locking-pin, which extends downwardly through an opening in the draw-head and engages a recess, h, in the outer edge of the shank E, as shown, which prevents the jaw from turning when the coupling is in use. A guard, t, at one side of the lower end of the locking-pin,is designed to enter a corresponding recess in the side of the pinopening and It will be observed that the recess 2" does not I extend to the outer end of the opening, that the end of the pin extends slightly beyond the inner wall, and that a curved slot, is, in the shank Eprovides a seat for the protruding end 7 of the pin when said pin is drawn upwardly to allow the coupling-jaw to be opened.

A slotted arm, I, extends outward from the upper end of the locking-pin, the inner end of said arm being bifurcated and inserted through a slot in the pin,where it is secured by turning the ends in opposite directions, as shown at i". A lifting-rod, K, centrally pivoted to the sill of the car, has its end j turned outwardly through the slot in the arm I. The said rod K extends to the outer side of the car, and is designed to operate the locking-key. Should t; coupling-jaw be broken away by accident, an ordinary link may be inserted in the recess Z and a coupling-pin inserted through the pinopening Z.

Having described my invention,what Iclaini 1s- 1. In acar-coupling, the combination of the draw-head having the recess for the shank, the couplingjaw provided with the shank portion having the trunnions thereon, and the crank-arm having the crank portion extending through the draw-head and into an opening in the trunnion provided with the guard to enter the recess, and the operating-bar, sub stantially as specified.
